I've been getting occasional short freezes of a couple of minutes.
But that's probably unrelated: as I have debugging turned on and am
deliberately stressing the fs poor performance is not unexpected.

I am currently trying to distill a test-case for crashing the fs.
It is going slowly, but I have managed to provoke a few panics,
including some new ones:
reiser4 panicked cowardly: reiser4[scatteredwrites(4506)]: reiser4_writepage

These are all for 2.6.18-rc4-mm1 + the small patch upthread.
